An apparatus for the treatment with physical agents is already knownwhich is characterized in that the treatment space comprises openingparts pivotally mounted by means of hinges on the fixed remainder ofsaid space which makes it possible for the patient easily to enter saidspace and to leave it without any difficulty.

According to a form of execution of this apparatus the treatment spacecomprises a fixed hood containing the lower part of the body of thepatient and a hood containing the middle and upper part of said body andpivotally mounted on the fixed hood by means of a transversal hinge.

The present invention relates to various novel forms of execution oftreatment apparatus of this type.

The present invention relates to an apparatus for the treatment withphysical agents which comprises a fixed hood containing the lower partof the body of the patient and a hood containing the middle and upperpart of said body and pivotally connected to the fixed hood by means ofa transversal hinge, said treatment apparatus being characterized inthat the movable hood is combined with means adapted to maintain saidhood in a raised condition in various positions and comprises innersource of radiation which makes it possible to subject the patientrecumbent on the treatment table to a remote irradiation, for example toa treatment with ultra-violet rays.

According to a characteristic feature of the invention the walls of themovable hood are lined inside with reflecting surfaces which makes itpossible to reflect towards the patient the rays sent out by the sourcesand directed laterally.

According to a form of execution of the invention the means formaintaining the movable hood in a raised position are formed of rackssecured to one of the hoods and capable of being hooked to a stopsecuredto the other of said hoods.

The present invention also extends to an apparatus for the treatmentwith physical agents, characterized in that the panel which forms theinclined plane is 'pivotally connected to the treatment table by meansof hinges arranged near the opening of the hood which makes it possibleto use said inclined plane according to its inclination either as apillow for a recumbent patient or as a back for a sitting patient orstill again as a. closing panel closing the opening of the casing.

According to a feature of the invention the treatment table comprises on.both sides of a median plate of resilient material, an annular groovefor the outflow of the sweat and a rib limiting this annular grooveexternally which makes it possible to prevent that said sweat flow pastthe annular groove intended to collect them.

According to another feature of the invention the treatment t ecomprises on its edges and externally with r spect to the ribs elongatedholes the axis of which i oblique with respect to the median plane ofthe apparatus which makes it possible to guide the air heated in contactwith the sources of heat arranged below the treatment table.

The present invention also extends to the hereinaiter described featuresand to their various possible combinations.

Treatment apparatus made in accordance with the invention are shown byway of examples in the accompanying drawing, in which: v

Figure 1 is a perspective view showing an apparatus for the treatmentwith ultra-violet rays in one of its positions of treatment.

Figure 2 is a longitudinal sectional view showing this apparatus withthe patient in a recumbent position. I

Figure 3 is a longitudinal sectional view showing the apparatus with thepatient in a sitting position.

Figure 4 is a View showing the rack for the adjustment of the hood.

Figure 5 is a perspective view showing the part of the apparatuscorresponding to the head of the patient.

Figure 6 is a perspective view with a cross-section showing thetreatment table supporting the patient.

Figure '7 is an elcvational view showing an apparatus mounted on wheels,and

Figure 8 is a view showing the balancing device.

The treatment apparatus in accordance with the present inventioncomprises a treatment table I resting on the ground through feet 15 andbelow which a lower casing 52 is suspended which contains heating meanssuch as electric resistors 23 arranged, for example, longitudinally(Figures 2, 3 and 6).

Mounted on the treatment table l is a fixed hood 5 intended to containthe lower part of the body of the patient. Pivotally connected to saidfixed hood 5 by means of a transversal hinge I is a movable hood 8showing a convex shape and carrying inwardly sources of radiation suchas, for example, an ultra-violet ray lamp ill secured to the highestpoint of this hood.

A rack :il pivotally mounted at 23 on each inner side face of themovable hood 8 can be hooked on the edge of a guide 42 secured to thecorresponding wall of the fixed hood 5.

Both said lateral racks make it thus possible to maintain the movablehood 8 in a suitable raised position (Figure 2) and to subject the wholebody of the patient to an irradiation. with ultra-violet rays sent outby the lamp 40 without said patient being enclosed in the apparatus.

In this case, the ceiling and the side faces 81, 82 of the movable hood8 form reflectors and reflect onto the patient in the direction of thearrows f1, f2 (Figure 1) the rays of which are directed laterally andwhich in a normal apparatus are lost for the patient.

To this end, said walls may be lined with sheets of polished or glazedaluminum having a high reflecting power. The upper part of hood 8 isprovided with advantage with a heat-insulated coating 55 (Figures 2 and3) of glass wool, for example, in order to prevent the radiation of theheat 1 outwardly.

Also, the apparatus according to the present invention may be used forthe treatment of the legs of the patient only, this latter sitting onthe treatment table I and his back being supported by the inclined plane9 the inclination of which is adjustable by means of racks E8 inaccordance with the French Patent No. P. V. 536,604 of June 18, 1947. 7

Thus, the patient is placed in a comfortable position which makes itpossible for him to read (Figure 3).

The panel 9 which forms the inclined plane pivotally connected to thetreatment table by means of hinges 44 and which thus serves either as apillow (Figures 1 and 2) 01' as a back (Figure 3) can also be tiltedback against the opening of the movable hood as shown in dotted lines inFigure (position 91) in order to close the opening of the hood and makepossible a rapid setting of the apparatus under temperature beforeintroducing the patient thereinto.

The opening 45 of the movable hood 8 (Figure 5) may be provided in aplate 46 sliding in slideways 4'! of the internal faces of the hood.Furthermore, this plate may be provided, in accordance with the presentinvention, with two holes 48 making it possible for the patient to passtherethrough his hands which are inside the hood and to raise said hoodwithout burning himself on inner sources of heat.

These holes make it also possible for the patient to execute underinfra-red radiations, for example, movements of gymnastics accentuatingthe perspiration.

In order to prevent the sweat from corroding the hinges 44 when theinclined plane is pivotally connected to the treatment table the rubberpanel 49 fastened to the inclined plane is extended inside the hoodthrough a drip-flap 491 (indicated in dotted lines in Figure 5) whichcovers said hinges 44.

The treatment table is formed with advantage as shown in Figure 6.

It comprises a strong panel I of wood, for example, on which a panel ofspongy rubber 2 is fastened in its central part.

On both sides of this panel the table I is provided with longitudinalgrooves 501, 502 and comprises on the outside of each groove aprojecting rib 5l1, 512 provided with elongated holes 53 the axes ofwhich are inclined with respect to the plane of table I. The boring axesof these holes are inclined downwardly and towards the median plane ofthe apparatus.

The hereinabove described treatment table makes it possible to collectthe sweat which fiows from the patient in the grooves 501, 502, the ribs5h, 512 preventing said sweat from flowing to the edges of the table andflowing out, for example, through the holes 53.

Holes which are particularly intended for the outflow of said sweateither into the inner hood or into particular vessels are provided atsuitable points of said grooves 501, 502.

The inclination of the axes of the holes 53 makes it possible to guidethe hot air currents coming from the resistors 23 in a directioninclined outwardly which makes it possible for said hot air better toenvelop the patient.

The heating resistors 23 arranged in the lower casing 12. may becombined, moreover, with burners for perfumes, with ozone producers orsubstituted by the latter in order to fight against the troublesomeodours produced by the perspiration.

The apparatus which forms the subject-matter of the present inventioncan be mounted on two wheels 54 (Figure '7) in order to facilitate itsdisplacement by raising the lower part.

The treatment apparatus may comprise for the heating of the space formedin the fixed hood 5 an upper transversal heating resistor 56 (Figures 2,3 and 4) as well as resistors 23, shown in Figures 2 and 3, arrangedbeneath the treatment table.

The movable hood may be balanced at least partially through springs 58(Figure 8) which facilitate the raising of this hood. Said balancing mayalso be obtained by means of counterweights.

The treatment apparatus which forms the subject-matter of the presentinvention may be made of metal such as steel plate or aluminum sheet, ofply-wood, of moulded plastic material or any other known materials.

The apparatus is provided with all the actuating and control devicesmaking it possible after a predetermined duration of the treatment tohave the current automatically switched off on the radiation sources.

Such a cut-out switch may be such that only some sources of heat remainswitched on in order that the patient may not be subjected to a toosudden change of temperature.

I claim:

In a cabinet for applying light or heat baths, a treatment table restingon the floor, a fixed hood fixed above this table to one of its ends forreceiving the patients feet, a movable hood capable, in its tilted-backposition, 01 enclosing the middle and upper part of the patients body,springs connected to said movable hood for balancing the same, rackssecured to one of said hoods, stops secured to the other hood andcapable of engaging the teeth of said racks to hold the movable hood invarious tilted positions, and sources of radiation fixed in said movablehood.
